water pump shaft seal
im in the process of replacing the seals on the timing cover (had oil running down from behind the opti)
my question is does the cover need to come off to replace the seal on the shaft the WP gos on. i think the big seal around the cam was the one leaking...but i want to replace this to just to be sure. don't want to tear it apart again
thanks

and the WP & Opti seals install "dry", no grease. Crank hub seal grease.
The WP drive seal will leak if installed wrong. Typically due to seal lip being folded back. Of course there is a "special tool" but you can just use a socket just .x" larger than the shaft the seal slides on. Slide the new seal by starting with the socket entering the seal from the top (this direction keeps the seal lip from folding over). Then transfer the seal from socket by holding socket against WP drive shaft. Once you get the seal started, tap in with small malet.
I've been told a cap from a "Sharpie" pen can be used as a tool.

Actually the water pump drive itself works perfectly, just bend the outer lip on the seal out and slide it onto the drive (on the smooth side of course) slide it over the drive and then transfer the seal over.

I believe there is a insert in the FelPro TC gasket set stating install dry as well.

All 3 seals in the timing cover will leak if they were lubed with oil during the install? I installed the seals w/ the cover off of the block. I put oil on the seals, then I saw the insert in the Felpro box. I tried wiping the oil off before installing.

The oil isn't going to be the problem if you installed the top seal then bolted it up. I didn't realize and when I was new to LT1's I did that and it will 100% pop the top water pump seal. You can install the bottom 2 then put it on and install the top one. The oil, if you cleaned it off I wouldn't lose any sleep over though.

I install the bottom two, then install the water pump seal once the cover is on. I wrapped electrical tape around the water pump driveshaft (just enough to get the seal to line up with the thick end of the driveshaft) slipped the seal to that little lip just before the thick part then wacked it on with a garden hose coupler and a hammer. It's a tricky seal because the metal will form to the WP driveshaft as you install it and it's very soft and easy to damage.
The first time I installed it I tried to put the WP seal on first and damaged it when installing the cover. Big learning curve with LT1s.
